[0020] Please refer to Figures 1-6, the present utility model provides a technical solution: a working bucket that can prevent load overrun, including a working bucket main body 1, a support bottom plate 5 is provided on the working bucket main body 1, a railing plate 3 is connected to the upper end of the support bottom plate 5, and a railing 2 is inserted and installed on the railing plate 3. A display screen mounting bracket 11 is provided on the side of the working bucket main body 1, and a display screen 10 is installed on the display screen mounting bracket 11. Below the display screen mounting bracket 11, there are a first clamp 1101 and a second clamp 1102 that cooperate with each other, and the first clamp 1101 and the second clamp 1102 are fastened to one of the railings 2. Above the support bottom plate 5, there is a weighing positioning plate 9. A clamping hole 902 is opened in the middle of the weighing positioning plate 9, and the size of the clamping hole 902 is larger than the size of the weighing sensor 7. And the mounting seat 8 is fastened and clamped in the clamping hole 902. This structure enables the mounting seat 8 to be detachably fixed relative to the weighing positioning plate 9 through the clamping hole 902, allowing the weighing sensor 7 to be disassembled from the clamping hole 902, which is easy to maintain the clamping hole 902. And the mounting seat 8 can relatively stably process the weighing sensor 7 and the weighing positioning plate 9. The bottom of the mounting seat 8 is clamped with the fixed part above the weighing sensor 7, and a protrusion in contact with the dust-proof cover 13 is provided at the top of the mounting seat 8. On both sides of the protrusion at the upper end of the mounting seat 8, a first handle 801 with a U-shaped structure is movably clamped. This structure enables the mounting seat 8 to also support the dust-proof cover 13, improving the stability of the dust-proof cover 13. At the same time, the dust-proof cover 13 covers the structure fixed in the weighing positioning plate 9, hiding the connection structure, which is easy to clean the working bucket main body 1 and convenient for handling goods. The first handle 801 can easily lift the mounting seat 8. And spring support columns 6 are evenly arranged on the side between the weighing positioning plate 9 and the support bottom plate 5. The spring support columns 6 are composed of support columns and springs. The support columns are fixed on the support bottom plate 5 stably, and at the same time, the support columns penetrate through the weighing positioning plate 9 movably, and the springs are located between the weighing positioning plate 9 and the support bottom plate 5, so that there is at least a 1-3 mm moving space between the weighing positioning plate 9 and the support bottom plate 5. And a dust-proof cover 13 is clamped and fixed at the upper end of the weighing positioning plate 9. A positioning frame 4 is clamped and welded on the outside of the support bottom plate 5, and the positioning frame 4 is screwed and fixed to the railing plate 3. The railing plate 3 has a clearance fit with both the weighing positioning plate 9 and the dust-proof cover 13. This structure can reinforce the stability of the connection between the support bottom plate 5 and the railing plate 3 through the positioning frame 4. An opening and closing door is provided between the railing plate 3 and the railing 2 for the access of the working bucket main body 1. The railing plate 3 also performs active limit processing on the weighing force-bearing structure composed of the weighing positioning plate 9 and the dust-proof cover 13. The spring support columns 6 provide a 1-3 mm moving space for the weighing positioning plate 9 for weighing processing. A weighing sensor 7 is installed in the middle between the weighing positioning plate 9 and the support bottom plate 5. The weighing sensor 7 selects a model that can be connected to the display. The current signal output by the weighing sensor 7 is converted into a signal format that the display screen 10 can recognize through an amplifier or a transmitter. And there is a cable 12 electrically connecting the weighing sensor 7 and the display screen 10.The side of the weighing positioning plate 9 is also evenly spaced with mounting holes 903, and the mounting holes 903 are screwed and fixed after passing through the column structure of the spring support column 6. A groove structure is provided inside the weighing positioning plate 9, and reinforcing ribs 901 are evenly spaced and welded in the groove of the weighing positioning plate 9. This structure enables the spring support column 6 to relatively stably install the weighing positioning plate 9 and the support bottom plate 5, allowing only relative displacement between the weighing positioning plate 9 and the support bottom plate 5, and enabling the weighing positioning plate 9 to be forced to move downward under the positioning of the support bottom plate 5 for weighing the goods on the dust cover 13. The display screen 10 is electrically connected to the weighing sensor 7, and can display the information weighed by the weighing sensor 7 in real time to control the loading quantity, avoid reminding only after the goods are overweight, and facilitate the use of the working bucket main body 1. The lower end of the dust cover 13 is in contact with the reinforcing rib 901, and positioning bumps 1301 are welded and fixed on both opposite sides of the dust cover 13, and a second handle 1302 movably penetrates through the positioning bumps 1301. This structure can improve the stability of the structure of the weighing positioning plate 9 by the reinforcing rib 901 and make the weighing positioning plate 9 and the dust cover 13 form a relatively stable whole, and the second handle 1302 can lift and disassemble the dust cover 13.

[0021] Working principle: When using this working bucket that can prevent load overrun, first open the access door composed of the railing 2 on the working bucket main body 1. The railing plate 3 makes the structure of the railing 2 stable. Then carry the goods into the working bucket main body 1. The surface of the dust cover 13 is flat, easy to clean, and at the same time easy to carry and move the goods. When the dust cover 13 is subjected to gravity, the dust cover 13 moves downward under the positioning of the spring support column 6 through the weighing positioning plate 9, allowing the weighing sensor 7 to weigh the goods and people on the dust cover 13. And through the cable 12 connected between the weighing sensor 7 and the display screen 10, the display screen 10 displays the detected weight information in real time for preventing load overrun. The reinforcing rib 901 makes the connection between the weighing positioning plate 9 and the dust cover 13 stable, ensuring the stability of weighing force. The mounting seat 8 is installed in the weighing positioning plate 9 through the clamping hole 902, and the dust cover 13 is clamped outside the weighing positioning plate 9, enabling the dust cover 13 to be lifted and disassembled upward through the second handle 1302, and then the mounting seat 8 is disassembled through the first handle 801, which can realize the convenient maintenance of the weighing sensor 7. The positioning bump 1301 is used for the connection and fixation of the second handle 1302 and the dust cover 13. The mounting hole 903 fixes the spring support column 6 on the weighing positioning plate 9. The support bottom plate 5 and the positioning frame 4 form the bottom support structure of the working bucket main body 1, allowing the support bottom plate 5 to perform the positioning process of weighing. The display screen mounting frame 11 is fixed on one of the railings 2 through the cooperation of the first clamp 1101 and the second clamp 1102, playing a role in installing and fixing the display screen 10, thus completing a series of work.

[0022] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
